Read MoreThe CQB100W Series is a high-performance range of isolated 100 W DC/DC converters designed for industrial, transportation, and embedded power applications requiring reliable regulation and wide input flexibility.
Built in a compact quarter-brick package, the CQB100W series features a 4:1 wide input voltage range and fully regulated single outputs, ensuring stable performance across fluctuating supply conditions. With efficiencies up to 88 %, robust protection functions, and 1500 VDC isolation, these converters deliver dependable operation in demanding environments.
The series supports multiple standard output voltages and includes remote on/off control, output trim functionality, and comprehensive protection against under-voltage, over-temperature, over-voltage, and over-current conditions. Compliance with IEC/EN/UL 62368-1 safety standards makes the CQB100W series suitable for globally deployed systems.
